INK-WELL.

SPECIFICATION forming part of Letters Patent No. 755,023, dated March 22,1904.

Application filed October s, 1903.

To all whom it may concern:

/ plied from a chamber or reservoir of sufiicient capacity to keep the dip-cup in working order for a long time.

My present invention has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, and general efiiciency; and with these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims. 7

In the accompanying drawings, Figure 1 is a vertical sectional view of a preferred form of my improved ink-well. 'Fig. 2 is a vertical sectional view showing a slightly-modified form of the same. Fig. 3 is a front view of the device as illustrated in Fig. 1.

Corresponding parts in the several figures are indicated by similar numerals of-reference. i

In carrying out the invention I provide a vessel 1, preferably constructed of glass and which may be of any suitable shape or outline. In Figs. 1 and 2 I have shown the said vessel as provided with a gable top, upon the front side of which are formed a plurality of shelves 2 adapted to support penholders, pencils, and the like. The vessel 1 is provided with a bottom 2, from which legs or supporting devices, as 3, depend; The said vessel is also provided with a horizontally disposed diaphragm or partition 4;, which separates the upper compartment or reservoir 5 from a lower compartment 6, which communicates with the compartment 5 through an opening 7 in the diaphragm I, said opening being surrounded by a depending flange 7 which regu- Serial No. 175,680- (No model.)

lates the point to which the ink may rise in the compartment 6.

The bottom of the device has a filling-opening 8, which is disposed in alinement with the opening 7 and which is normally closed bymeans of a stopper 9.

The bottom 2 of the its upper side with a lug 10, with which is pivotally connected a lever 11, one end of which extends upwardly through the opening 7 and carries a valve 12, adapted to close the said opening when the said valve is lowered. The opposite end of the lever 11 carries a float 14, which when the ink rises in the compartment 6 will cause the valve 12 to be depressed, and thereby to close the passage 7 In the front side of the body or casing of the device is formed a dip-cup 15, which is inclined inwardly from the front face of the body of the receptacle.- In Figs. land 3 I have shown a preferred construction whereby the said dip-cup is simply a cavity in the front wall of the receptacle, which latter normally occupies a vertical position. An opening or ink-passage 16 connects the dip-cup with the compartment 6 at the bottom 2 of the latter, and an air-vent 17 is formed in the wall which separates the compartment 6 from the dipcup, at the upper end of said wallthat is to say, directly belowthe bottom 4 of the main compartment 5 of the reservoir. Under the construction shown in Fig. 2 I provide the dip-cup with a forwardly-extendinglip 18, which may facilitate the admission of the penholder. The omission of said lip, as in Figs. 1 and 3, will, however, serve to prevent the admission of dust into the dip-cup and the annoyance caused thereby.

The operation of this device in any of its forms will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. To fill the receptacle, it is simply inverted and the stopper 9 is removed, when the fluid may be readily introduced through the openings 8 and 7 into the main compartment of the receptacle. The stopper 9 being replaced, the device may be returned to its normal position and ink will naturally flow from the compartdevice is provided on ment 5 through the opening 7 into the compartment 6, where it stops on a level with the lower edge of the flange 7. Under ordinary circumstances the ink will not rise above this level either in the compartment 6 or in the dip-cup. In case, however, of the unusual expansion by heat or otherwise'of the contents of the compartment 5 an additional quantity of ink will be forced into the compartment 6, where it will rise between the opening 16 and the vent 17. This rise, however, will be speedily checked by the valve 12, which when the rise of the level in the compartment 6 takes place will be lowered by the joint action of the float 1e and the lever 11. It is obvious that the stronger the downward pressure upon the valve 12 the more tightly will said valve be fitted to the opening The dip-cup in any case will be extended into the solid glass of which one of the legs 3 is formed, and in the absence of the lip 18 there will be no protuberances which will be liable to break off by rough handling of the device.

I have in the foregoing described a simple and preferred form of my invention; but I desire it to be understood that I do not limit myself to the precise structural details herein shown and described, but reserve the right to any changes, alterations, or modifications which may be resorted to within the scope of my invention and without departing from the spirit or sacrificing the utility of the same.

Having thus described my invention, I

claim 1. An ink-well having a horizontally-disposed diaphragm provided with an opening and a downwardly-extending flange surrounding said opening, a stoppered opening in the bottom of the vessel in alinement with the opening in the diaphragm, an outwardlyopening dip-cup, an ink-passage connecting the latter with the lower compartment of the receptacle, and an air-vent connecting the dipcup with the lower compartment directly below the diaphragm.

2. An ink-well comprising a receptacle havingan approximately horizontal diaphragm provided with an opening, connecting the upper and lower compartments formed by said diaphragm, a flange surrounding said opening and extending to the normal ink-level in the lower compartment, a dip-cup connected with the lower compartment by an ink-passage and an air-vent, a lever fulcrumed in said lower compartment and having one end extended upwardly through the opening in the diaphragm, a valve carried by said upwardly-extending end of the lever, and a float carried by the opposite end of the latter.

3. In a fountain ink-well having a main compartment or reservoir, a lower compartment, a dip-cup corinected with said lower compartment, a diaphragm separating said compartments, and an opening in said diaphragm, in combination with a float-operated valve adapted to close the opening in said diaphragm.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
